Taiwan Semiconductor Manufacturing Co. (TSMC) has captured approximately 73% of the worldwide semiconductor foundry market, underscoring a level of dominance rarely seen in any global industry. According to Counterpoint Research, the company held that share in the second quarter of 2026 — its second consecutive quarter at that level. Its closest competitor, Samsung Foundry, sits at roughly 5.9%.

The figures highlight how far the gap has widened between the world's largest contract chipmaker and the rest of the foundry industry.

The Numbers Behind the Dominance

TrendForce data largely mirrors the Counterpoint findings, pegging TSMC's Q2 2026 share at 72.5%, with quarterly revenue approaching $40.2 billion. The figure represents a 12.1% increase from the prior quarter, driven by full utilization of advanced manufacturing capacity and a boost from smartphone builds. That two independent research firms land within half a percentage point of each other gives the concentration figure unusually solid corroboration.

For the full year 2025, TSMC recorded $122.54 billion in foundry revenue, a 36.1% year-over-year increase that gave it a 69.9% share for the calendar year.

Advanced nodes — chips built on 7-nanometer process technology and below — accounted for 74% of TSMC's wafer revenue in 2025. These chips power AI training clusters, high-end GPUs, and the servers that companies including Nvidia, AMD, and Apple depend on.

Samsungry, despite being part of one of the world's largest conglomerates, has remained in the 5.9% to 7.2% range across recent periods. China's SMIC holds about 5.4%, while UMC and GlobalFoundries each occupy single-digit shares below 6%.

Why the Gap Keeps Growing

TSMC's process technology leadership on 3nm nodes is well established, and initial contributions from its 2nm node are already appearing in the revenue mix. Each generation of chip shrinkage requires billions of dollars in research and development and capital expenditure, and TSMC's massive revenue base allows it to reinvest at a scale competitors cannot match. The pace at which 2nm climbs through the revenue mix is the next data point to watch, since leading-edge node leadership is what has driven the gap to date.

The AI boom has accelerated this dynamic, with increased wafer shipments and rising average selling prices on leading-edge nodes both contributing to revenue growth.

Advanced packaging adds another layer to the competitive barrier. Techniques such as TSMC's CoWoS (Chip-on-Wafer-on-Substrate) packaging are essential for assembling the complex multi-chip modules that AI accelerators require.

What It Means for the Broader Chip Landscape

Because TSMC is the sole manufacturer capable of producing the world's most advanced chips at scale, it holds significant pricing power, and rising average selling prices on leading-edge nodes flow through to margins, particularly when capacity is fully utilized.

The crypto mining hardware sector offers another perspective. TSMC fabricates the chips inside Bitmain's latest ASIC miners, as well as many of the GPUs used for proof-of-work mining and AI-adjacent workloads. Any constraint on TSMC's capacity or pricing therefore ripples directly into the cost structure of mining operations worldwide.

The distance between TSMC's 73% share and Samsung's 5.9% is now wider than Samsung's entire share — a measure of just how concentrated contract chip manufacturing has become.
